THE PLANT KINGDOM
These "naked seed" plants, like pine trees, produce seeds in cones rather than flowers.
What are Gymnosperms?
Petunias and zinnias are examples of this type of plant that lives for only one growing season.
What are Annuals?
This green pigment is essential for photosynthesis and is found in the chloroplasts of nearly all plants.
What is Chlorophyll?
This group of flowering plants is named for having two "seed leaves" or cotyledons upon germination.
What are Dicots?
This term describes plants like peonies or oak trees that persist for many years, often returning season after season.
What are Perennials?
In a plant's vascular system, this tissue is responsible for transporting water upward from the roots.
What is Xylem?
Lilies, grasses, and corn belong to this group, characterized by parallel leaf veins and flower parts in multiples of three.
What are Monocots?
A carrot is a classic example of this group, which spends its first year growing roots and its second year producing seeds.
What are Biennials?
These tiny pores on the underside of leaves allow for gas exchange, letting carbon dioxide in and oxygen out.
What are Stomata?
Most flowering plants fall into this category, which uses fruits to protect and disperse their seeds.
What are Angiosperms?
This is the name of the diploid, spore-producing phase in a plant's "Alternation of Generations" life cycle.
What is the Sporophyte?
This sugary fluid is transported throughout the plant via the phloem.
What is Sap?
This is the specific rank in the taxonomic hierarchy that sits directly between "Kingdom" and "Class."
What is Phylum?
While perennials live long lives, this term describes the natural aging and death process of plant organs, like leaves falling in autumn.
What is Senescence?
This waxy, waterproof layer covers the leaves of most land plants to prevent desiccation (drying out).
What is the Cuticle?
